I don't have much advice, other than that I've heard taking biotin may help. I don't know--I've been taking it since the surgery, but my hair has thinned drastically anyway. I've been told it will grow back, so I'm just trying to hang tough and wait for that--but I'm not thrilled to look in the mirror. I cut my hair, hoping that the shorter length might help, but it doesn't make much of a difference. I'm wondering if anyone has gotten a permanent at this stage and whether that helped at all?
